Planets in our solar system to rotate clock wise is Venus and Uranus.
All other planets rotate anti-clock wise.
A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.[1] The Solar System has eight planets by the most restrictive definition of the term: the terrestrial planets Mercury, Venus, Earth, and Mars, and the giant planets Jupiter, Saturn, Uranus, and Neptune. The best available theory of planet formation is the nebular hypothesis.
Sun :
Sun do not rotate.
When you think of a day, you normally think of one cycle through one day and one night. That is called a solar day. Another way to measure a day is to count the amount of time it takes for a planet to completely spin around and make one full rotation. This is called a sidereal day. On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
Inner Planets
The first four planets from the Sun are Mercury, Venus, Earth, and Mars. These inner planets also are known as terrestrial planets because they have solid surfaces.
Outer Planets
The giant planets in the outer solar system don't have hard surfaces. Instead, they have swirling gases above a core. Jupiter and Saturn are gas giants. Uranus and Neptune are ice giants.
Time taken and speed of rotation of planets
- Mercury: 58d 16h, 10.83 km/h
- Venus: 243d 26m, 6.52 km/h
- Earth: 23h 56m, 1574 km/h
- Mars: 24h 36m, 866 km/h
- Jupiter: 9h 55m, 45,583 km/h
- Saturn: 10h 33m, 36,840 km/h
- Uranus: 17h 14m, 14,794 km/h
- Neptune: 16h, 9,719 km/h
Dwarf Planets
Dwarf planets include longtime favorite Pluto, Ceres, Makemake, Haumea, and Eris. Ceres is the only dwarf planet in the inner solar system. It's in the main asteroid belt between Mars and Jupiter.
Ceres Facts
Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter, and it's the only dwarf planet in the inner solar system.
Natural Sattilities of planets :
Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth’s Moon. Since it was named before we learned about other planetary satellites, it is called simply “Moon.”
The current tally of moons orbiting planets in our solar system is 293: One moon for Earth; two for Mars; 95 at Jupiter; 146 at Saturn; 28 at Uranus; 16 at Neptune; and five for dwarf planet Pluto.
Mercury : No moon.
Venus : No moon.
Earth : One natural sattilitie called Moon. The Moon makes Earth more livable by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years. The Moon rotates exactly once each time it orbits our planet.
Mars : Mars has two moons, Phobos and Deimos. Both are thought to be captured asteroids, or debris from early in the formation of our solar system. Phobos is the larger of Mars' two moons. It orbits Mars three times a day, and is so close to the planet's surface that in some locations on Mars it cannot always be seen. Phobos is nearing Mars at a rate of six feet (1.8 meters) every hundred years. At that rate, it will either crash into Mars in 50 million years or break up into a ring. Deimos is the smaller moon. It orbits Mars every 30 hours.
Jupiter : Jupiter has 95 moons that have been officially recognized by the International Astronomical Union. But the number doesn't capture the complexity of the Jovian system of moons, rings and asteroids. The giant planet has thousands of small objects in its orbit. The four largest moons of Jupiter—Io, Callisto, Ganymede, and Europa—were the first objects in the solar system discovered with a telescope.
Saturn : Saturn has 146 moons in its orbit, more than any other planet. The moons range in size from larger than the planet Mercury – the giant moon Titan – to as small as a sports arena. The small moon Enceladus has a global ocean under a thick, icy shell. Scientists have identified both moons as high-priority science destinations for future deep space missions.
Uranus : Uranus has 28 known moons, including five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon.The moons are sometimes called the "literary moons" because they are named for Shakespearean characters, along with a couple of the moons being named for characters from the works of Alexander Pope.
Neptune : Neptune has 16 known moons. English merchant and astronomer William Lassell discovered the first and largest moon – Triton – on Oct. 10, 1846, just 17 days after a Berlin observatory discovered Neptune.
